• Have written various python unit tests that verifies the integrity and consistency of python modules for the content manager application.
• Have ported a QT based User Interface(UI) content manager application into a QML based user interface.
• Have written C++ application that loads QML UI and vice versa (QML UI that interacts with C++ applications in the content manager UI application).
• Helped debug multithreaded User management application in C/C++ to remove subtle errors occurring when a user changes state in the User management state machine.

Confidential

Senior Software Engineer

Responsibilities:

• Enhanced the payment transaction for Confidential to support various functionality.
• Added a QTableWidget widget to the SVT UI application to retrieve customer info and fill the item-based table.
• Have written Linux shell scripts that copies log files and query based on user inputs.
• Resolved merge conflicts in ClearCase.
• Have added functionality to cashout transaction that superimpose electronic signature from Pinpad to an electronically created document.
